Robinho has returned to Italy as AC Milan struggle to agree a fee with Santos over his sale.
Milan chief Adriano Galliani is currently in Brazil working on the sales of Robinho and Alexandre Pato.
While the latter is on the verge of a move to Corinthians, selling Robinho is proving to be more problematic.
Santos are offering €7 million, while Galliani is insisting on €10 million.
